A) For purposes of calculating the electric field in the region around them, the spheres can be considered the same as if they were point charges centered at the middle of the actual spheres. What is the electric field (magnitude and direction) at the midpoint between the two spheres?
B) What is the potential difference between the two spheres?
C) The spheres are briefly touched together, then separated. Now what is the charge on Sphere A?
D) Now what is the potential of Sphere B?
E) Now what is the potential difference between the two spheres?
